1 Claim.

The present application constitutes a division of a parent application Serial No. 402,024 led October 24, 1929; and relates to a particular form of printing surface holder which While adaptable for general usage is particularly adaptable for use in the type of machine` disclosed in the above noted parent application.

The construction and operation of the device forming the subject matter of the present case will ce fully disclosed hereinafter, reference being had to the accompanying drawing, of which:

Fig. 1 is a transverse sectional elevation;

Fig. 2 is a longitudinal sectional elevation taken on the line 2 2, Fig. l; and

Fig. 3 is a transverse sectional elevation similar to Fig. 1, and showing a modification of the invention.

The present application concerns means for supporting a printing block, having type on one face thereof, in a manner to procure and facilitate proper positioning of the printing effected by the type on the block in a predetermined position on each of a series of sheets or in definite relation to each other on and relative to the margins of said sheet or a continuous web either of which is conned to movement in a denite path past the printing block.

In the present instance the printing block is indicated at |3|. The type block |3| is adapted to be carried by a supporting bar |32 which at its opposite ends is secured to a pair of axially aligned wheels E33, 33 secured to a shaft |34 which is parallel to the block-supporting bar |32.

The wheels l33, |33 are each provided with an inverted T-shaped or undercut groove |53 formed in the peripheral face of the wheel and extending circumferentially thereof, completely around the Wheel.

The bar |32 is provided with a longitudinal slot |53. Secured in the block |3| and passing through the slot in the supporting bar |32 is a stud |5| on the inner Yend of which is a butterfly nut H52 by which the block |3| is rigidly secured to a supporting bar |32, and by means of which the block |3| may be moved to any desired position transversely of the machine for positioning the identifying data at any desired point (Cl. 10b-375) with respect to the side edges of the sample being printed upon.

To insure parallel positioning of the block |3| with respect to the supporting bar |32 the said block is provided with projections |53 at its op- 5 posite ends respectively and which extend into the slot |59 in the supporting bar |32.

As shown in the drawing, the supporting bar |32 is secured to the wheels o-r heads |33 by means of bolts |54 having rectangular heads |55 l0 which nt within the T-shaped grooves |56 which extend oircumferentially of the wheels |33. By this means the bar |32 and consequently the type block |3| may be adjusted to any angular position with respect to the axis of the shaft |34 15 for positioning the block of identifying data at any desired position intermediate the end -edges of the sample sheet being printed upon.

For the purpose of counterbalancing the Weight of the supporting bar |32 and the type block |3| 20 a counterweight |51 is adjustably mounted on and extends between the wheels |33, |33 in substantially diametrically opposite relation to the said supporting bar 32.

As shown in Fig. 3, a relatively long type block 25 |3|a may be used providing for a considerably greater number of type slugs, such a type block being supported by two or more of the supporting bars |32 which may be spaced, as illustrated in Fig. 3, circumferentially of the Wheels |33 and 30 adjacent the respective ends of the type block l3la.

The shaft |34 is suitably mounted for rotation whereby the printing surface will revolve in contact with a sample carried by a suitable platen 35 for pressing the sample into printing contact with the type face on the printing block |3|.

I claim:

In a printing machine, the combination of a type block, a carrier bar secured to said type 40 block, a pair of axially aligned supporting wheels respectively `secured to the opposite ends of said carrier bar, means for adjusting the carrier bar circumferentially of the supporting wheels, and means for adjusting the type block transversely 45 on said carrier bar.
